REVERSIBLE CO RRUGATED GAG E-CUTTER.

SPECIFICATION forming part of Letters Patent No. 633,472, datedSeptember 19, 1899.

Application filed June 22, 1898. Serial No. 684,167 (No model.)

To aZZ whom it may concern: I

Be it known that LWILLIAM G.MoLELLAN, a citizen of the United States,residing at Anaconda, in the county of Deer Lodge and State ofMontana,have invented new and useful Improvements in ReversibleCorrugated Gage-Gutters, of which the following is a specification.

This invention relates to reversible corrugated gage-cutters, and hasfor its object to provide an improved construction of reversible cuttingdevices applicable to knives or to rotary cutters or to stationarycutters for preparing fruits and Vegetables in culinary operations andfor other purposes.

The invention consists in a gage-cutter having the novel features ofconstruction hereinafter described and claimed.

In the annexed drawings, illustrating my invention, Figure 1 representsthe invention as applied to a vegetable-cutter that is to be heldstationary while in use. Fig. 2 is a longitudinal section of the same.Fig. 3 shows a knife with gage-cutter corrugations formed longitudinallyin the knife-blade. Fig. 4 is a view of a knife having the series ofgage: cutter corrugations arranged transversely of the knife-blade. Fig.5 shows my invention as applied to a rotary cutter.

In the construction of a cutter according to my invention I take a pieceof steel or suitable sheet metal and form therein a series of parallelconcavo-convex corrugations 1, alternating with a corresponding seriesof slits 2, located between said corrugations. The concavities of thecorrugations are presented alternately to the opposite sides of themetal. Both edges of the corrugations are ground to form cutting edges 3and 4, which are so arranged that the cutter presents cutting edges inboth directions and on each side. This construction of cutter isapplicable to a great variety of uses, some of which may be mentioned.In Fig. l, for instance, I have shown a vegetable-cutterof the kindwhich is to be held stationary while the vegetable or fruit is to bemoved forward and back across the plurality of cutting edges, being thuspared or cut into slices. For a cutter of this character I provide arectangular or somewhat oblong metal sheet 5, in which the corrugations1 with intervening slits 2 and cutting edges 3 4 are formed. A suitableframe 6 is provided to facilitate handling this cutter. It will beobserved that the cutter-plate is provided with a sufi'icient margin 7for purposes of strength and req: uisite stiffness.

Another application of my invention is illustrated by the knife shown inFig. 3, in which the concavo-convex corrugations 1 and intervening slits2 are arranged longitudinally of the knife-blade 8 and adjacent to thehandle 9, which may be integral with the blade,or the knife-handle maybe constructed and attached in any preferred manner. In a knife-blade ofordinary widthsay about one inchthere may be threelongitudinallydisposed corrugations of about equal width and presentingfour cutting edges on each side, two being formed by the sharpened outeredges of the blade. The end portion of the knife-blade 8 may be leftuncorrugated for ordinary use, and, if.desired, a point 10 may beprovided suitable for coring fruit or digging out undesirable portions.In handling this knife the cutting edgesof the corrugations are usefulfor peeling or paring to a gage and without waste, the slits 2 affordinga clearance for the peeled portions of fruits or vegetables, and beingprovided with cutting edges both sides of the blade the knife can beused equally well in either hand.

As shown in Fig. 4, a knife-blade may be slitted and corrugatedtransversely, if preferred. The corrugations l are concavo-convex, withthe concavities and cutting edges of alternate'corrugations presented toopposite sides of the blade, so that it cuts on both sides and in bothdirections of movement. The transversely-corrugated portion of the knifeblade has uncut margins 7, that strengthen the blade. both sides up anddown and will make a plurality of slices at each stroke, according tothe number of cutting edges presented on the two sides of the knife inthe direction of out.

In Fig. 5 I have illustrated my invention as applied to a rotary cutterfor slicing fruits, vegetables, and other substances. This rotary cutteris preferably in the form of a conoidal drum 11, carried on acrank-shaft 12, that is mounted to rotate in suitable bear- The knifecuts on ings. The construction and arrangement of the corrugations 1 andtheir cutting edges are the same as already described with reference tothe preceding figures of the drawings. A concaved shelf or hopper 13 isarranged at an angle adjacent to a lower part of the rotary cutter forthe purpose of receiving the article to be cut or sliced. The form ofthis shelf 13 and its arrangement with relation to the rotary cutterwill cause the vegetable, fruit,- or other article to continually pressdown and against the side of the drum as it is rotated in the directionof the arrow, and thus the slicing of the article will proceedcontinuously. The sliced material enters the drum through the slits 2,that alternate with the cutting corrugations. The larger end of theconoidal drum is open, and thus the sliced contents are fed outcontinuously. This rotary cutter or drum is preferably constructed inthe form of a skeleton frame, to which is secured the sheet-metalcovering in which the cutting corrugations 1 are formed. Theconstruction of these corrugations in the manner described, with theconcavities and cutting edges of alternate corrugations on oppositesides, so as to present cutting edges on both sides of the metal and inboth directions of drum rotation, will permit removal and reversal ofthe corrugated plate or sheet-metal drum-covering whenever the cuttingedges of the exposed side have become worn, and obviously the drum willoperate in either direction of rot-ation if the material to be cut isproperly presented.

The reversible double-acting construction of cutter that I havedescribed can be readily applied in cutting implements of various kindsfor purposes of paring, peeling, shavin g, slicing, &c. The convex sideof each corrugation projects in line with the cutting edges of adjoiningreversely-placed concavoconvex corrugations to act as a guide or gagefor the cutting edge on either side, and by having the corrugations ofuniform dimensions sharpened on both edges or margins and with theconcavities of alternate corrugations presented to opposite sides and ofsuitable depths there is provided a reversible cutter of any requiredgage. The construction described can be applied to spoke-shaves and tovarious forms of knives and cutters besides those that are here shown.The cutter is durable, comparatively inexpensive, and is readilyapplicable to a great variety of uses.

As shown in Fig. 1, it is preferable to arrange the cutting edges of thecorrugations at an angle of about thirty degrees, more or less; but thismay be Varied as desired.

What I claim as my invention is- The herein-described reversiblegage-cutter'provided with a series of parallel alternately-reversedconcavo-convex corrugations separated by intervening slits and havingboth edges of all corrugations sharpened, the concavities of alternatecorrugations and the said cutting edges thereof being presented toopposite sides of the cutter and the convexed side of each corrugationbeing made to project in line with the cutting edges of adjoiningreversely-placed concavo-convex corrugations to act as a guide or gagefor the cutting edge on either side, whereby the said cutter presents aplurality of gage-cutting edges on both sides and in both directions ofcutting action throughout the whole series of alternately-reversedconcave-convex corrugations, substantially as shown and for the purposespecified.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
